Given numbers are 259, 397, 905, 247
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(259, 397) = 102823
GCD(259, 397) = ( 259 x 397 ) / 102823
= 259 / 397
= 259
Step2:
LCM(1, 905) = 905
GCD(1, 905) = ( 1 x 905 ) / 905
= 1 / 905
= 1
Step3:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
So, Greatest Common Divisor of 259, 397, 905, 247 is 1
